Clarity of Daytime and Night Vision: When wireless baby monitor systems with screens were first introduced onto the market they used somewhat outdated display technology that made for a grainy, distorted and often unreliable picture. Newer baby monitors use a liquid crystal display similar to the ones used in your smart phone and other consumer electronics, so these HD video baby monitors tend to have very nice color contrast and high resolution, and are also substantially more reliable. All of the stand-alone baby monitors we list above have high-quality displays, and we do not recommend some of the relatively old fashioned ones that can still be found on the market. Of course, night vision doesn't use color - so the display will be either grayscale or show a slightly green hue. That's important to keep in mind before you try it out for the first time; not even military special operations have color night vision, so don't expect anything amazing, even from the best baby monitor!
For the parent devices of dedicated monitors, the battery life ranged anywhere between 6.75 and 12.75 hours. The Wi-Fi options are harder to gauge given that the battery life depends on the kind of device used, whether or not it is being used for other applications simultaneously, and how old the battery is in the device. In general, however, we feel it is relatively safe to say that most will work longer than the best dedicated monitor battery if the device is dedicated for use with the monitor only and is not running other applications simultaneously.

As much as new parents want to be in the room with baby at all times, sometimes a baby monitor is necessary (like when you’re having a dinner party — or just want to watch Insecure in the next room). To help navigate the vast, confusing universe of baby monitors, we spoke to Lauren Kay, the Bump’s deputy editor, and Dave Baldwin, Fatherly’s former gear-and-tech editor and current play editor, about their recommendations, from traditional video monitors to smart-tech-enabled devices that can even track how your baby is sleeping. Add one of these to the baby registry.

The Nest Cam Indoor Wi-Fi and the LeFun C2 720P Wi-Fi came in a close second to the iBaby M6S Wi-Fi for features, both scoring an 8 of 10. Because these cameras are designed more with surveillance in mind and are not solely marketed for baby, they have several features that make parents lives easier, but not anything fancy and fun for baby. They do offer 2-way communication, but no lullabies or environmental sensors. Given that many parents already have "noise makers" (aka lullabies) covered by way of another product, the lack of this feature isn't a deal breaker in our book. So while these Wi-Fi cameras lacked the gadgetry fun of humidity sensing and the other bells of the iBaby M6S Wi-Fi, they still got the job of monitoring done in a way that is easy for parents to use. The bonus of the Nest Cam Indoor Wi-Fi camera is that it can be used for multiple applications when baby gets older and no longer needs an overnight monitor. This monitor can easily shift for use as a nanny cam, security, or pet camera. We think this takes the sting (if there is some) out of its lack of baby fun features, which in the end, most parents usually stop using when the novelty wears off.
One minor but potentially annoying flaw: The “on” lights on the parent unit are a touch bright, and you may be more sensitive to them since you’re likely to have the unit within view as you sleep. They appear as greenish yellow light from the face of the unit, and a charging light, which is blue when it’s fully charged. Depending on how sensitive you are to light, you may want to lay the display face down on a nightstand or cover the status lights with tape.
This type of monitoring device attaches to your baby via their diaper, clothing or as a sock depending on the model. Most of the wearable options alert in the room and only a handful send a message to a parent device (smartphone or similar). In our experience, many of these have high false alarms from moving and crawling babies or high Electromagnetic Field (EMF) Levels (which we try to avoid). The Snuzo Hero SE is a cost-effective wearable with a unique vibration feature and very low levels of EMF.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
